The wires just unplug and there is nothing else holding it

But what about the cables? In the Deep Workers those all go through a hydraulic guillotine.

>> Hi All,
>> A while back I mentioned that I am mounting my vertical thrusters on permanent  magnets.  I welded flat seats to the hull for the magnets to sit on and I tried it out.  I started with 3 magnets per motor and that was not enough.  I add 2 magnets per motor to 5 each.  So far it is great, and I can not pull the mounts off by hand unless I torque on them from the side.  I will finish mounting them and then do a weight test.  This means all my motors and arm etc jettison.

I once crawled out from painting the underside of the sub only to have a chain part seconds later and the sub drop two feet onto the floor. It probably registered on a seismographs. Fortunately I lived to learn how exceptionally stupid I'd been. I now have the biggest baddest sub supports you can imagine, and a permanent allergy to going under the sub.

>> Hi All,  I always talk about the things that get done and the progress.  The fact is with all the success comes failures.  I broke my nice fibreglass battery box by being stupid.  It took me a full 4 days to fabricate a new one from 1\8 steel plate and then transfer the electric bits and batteries.  Then the task of installing the 350 lb box without separating the chassis from the sphere.  Its not all smooth sailing!
